Lester quotes from Doctor Who

[while examining an infected man who's going to be shot by his comrades] The man is sick, he needs treatment!

Lester

There is no treatment. All we can try to do is stop the infection spreading!

Sorry, gentlemen, I can't allow it.

Commander Stevenson

You can't allow it?

My colleague is a doctor of medicine and I'm a doctor of many things. If we could examine him-

[interrupting him] Commander, I'm afraid we have to kill these people, too. They brought the plague in here.

Who's the homicidal maniac?

Lester

Why don't we just wait here?

I think my idea is better.

Lester

What is your idea?

I don't know yet. That's the trouble with ideas - they only come a bit at a time.

Lester

Harry, don't touch it! Open that buckle and you'll be blown to kingdom come.

Harry

You mean it's booby-trapped?

Lester

These buckles can't be opened until the Cybermen beam the release signal.

Harry, [sits up] were you trying to undo this?

Harry

Well, naturally.

Did you make the rocks fall, Harry?

Harry

Well, I suppose I must have done that, yes...

...Yes, yes... [starts laughing, and then roars] HARRY SULLIVAN IS AN IMBECILE!!!
